Shared and unique characteristics of school, cyber and family victimization among school-aged children in Hong Kong

Victimizations from online and offline violence, such as sibling violence, school violence and witness of family violence, both have negative associations with victims' mental health and may share similar individual and family characteristics. This study aims to explore the common and differentiated characteristics in the prediction of school, cyber and family victimization and whether there are unique associations within these victimization types. We employed a two-stage stratified sampling method to collect a representative sample of 5567 children aged 3–17 from a cross-sectional, school-based survey in Hong Kong. Results showed that all types of child victimization, including sibling, school and cyberbullying, as well as the witness of violence at home, were positively correlated with each other. Children's age was positively related to the occurrence and cooccurrence of all types of child victimization. Frequent family residential mobility and parents' higher education level were positively related to all types of children's victimization. The scores of all aspects of children's paediatric quality of life were found negatively related to children's school victimization. This study provides insight into the unique and shared elements of children's online and offline victimization. Knowledge of the distinguished familial gradients of child victimization at home and beyond could benefit the development of child victimization prevention.
